Nahan Kentut Simulator is an Android game developed by CascadePlay that challenges players to hold in their farts for as long as possible. The game follows the story of Bayu, a high school student who loves to eat fried sweet potato. Because of his love for this snack, he always holds in his farts. The objective of the game is to help Bayu hold in his farts for as long as possible in various public places.

The game offers five levels, each consisting of four different public places where farting is usually prohibited. Players must complete challenging objectives in each level while holding in their farts. The longer they hold in their farts, the higher their score. The game also features a star collection system that helps players earn even more points.

To play the game, players must balance Bayu's body by tilting their smartphone left or right. The game offers a fun and challenging way to test your fart-holding skills.
